Many people overcarb...I've run a 12.40 in my Duster with a stock stroke 340 and Holley 650 carb.



I have holley 650 that I got on a 318 in a parts car, the carb looked brand new.

I got it out over the weekend and want to try it on my 340. But man is it hard to pull off a great running 600. Gonna try it here soon, maybe tonight.
